Forecasters are keeping a close eye on a developing weather system that could affect the Poconos Sunday into Monday, potentially, according to some estimates, bringing up to a foot of snow to the region.

Tom Lutz of poconowx.com said this storm has the potential to be a major storm, but a lot of factors still have to be determined, he said.

Other prediction services have called for 12 to 18 inches of snow in the region and others are solidly forecasting 6 to 12 inches.

According to Lutz, this is what we know right now:

• A storm system will move across the country this weekend

• The system will bring severe/winter weather to the Plains this weekend

• As the storm moves across the Plains and the Ohio Valley it will become clearer where the axis of heaviest snow will fall in the Mid-Atlantic

• There will be a very tight thermal gradient extending across the Ohio Valley to New England

• This gradient will determine where areas of enhanced lift will be

• These regions will experience the most significant winter weather

• This storm also has the potential to last for a long period of time, which could raise accumulations
